We would still get the annoying newbie threads.
"Hey guys I just read in the FAQ that I can drink my winny. Is this true? Just looking for some confirmation. Thanks"
Or
"The FAQ says 'x' but my bro in the gym told me 'y' and now I am not sure what I should do. BTW i am 12 is this too young to start. If it is too young, I have a friend the same age who is going to start anyways so please at least help me tell him what he should do since he is going to start anyway."
Having said that, I do like the idea of the FAQ section, but I dont think it would totallly solve the problem.
